How to prepare your ERP for Tax Reform: Practical guide for companies

Tax Reform is a reality in Brazil and will begin to be implemented in 2026. It represents one of the biggest tax changes in the last 50 years, with the replacement of several taxes by new models, such as the IBS (Tax on Goods and Services) and the CBS (Contribution on Goods and Services).

If your company uses an ERP, it is essential to understand that, if it is not prepared, your operation may face serious tax, financial and operational problems.

But after all, how to prepare your ERP for Tax Reform? In this article, you will learn the essential steps to ensure that your company is ready for this new scenario.

Why does Tax Reform directly impact your ERP?

The ERP works as the nerve center of your company. It integrates tax, accounting, financial and operational processes. With the reform, significant changes occur in:

Tax structure, with the elimination of ICMS, ISS, PIS, Cofins and IPI.

Tax calculation rules.

Additional obligations and tax returns.

Issuing invoices and accounting records.

If the ERP does not keep up with these changes, your company may face challenges such as:

Incorrect tax calculation.

Tax fines and penalties.

Suspension of operational and tax processes.

Loss of competitiveness and increased costs.

7 steps to prepare your ERP for Tax Reform

1. Review your tax and fiscal processes
Before thinking about updating the system, it is necessary to map and review all of the company's tax processes. Understand exactly which areas will be most impacted: sales, purchases, finance, logistics or accounting.

2. Update product and service records
The correct tax classification will be even more relevant. It is essential to review data such as NCMs, CSTs, CFOPs, service codes, as well as customer and supplier information. This ensures that the ERP performs accurate calculations and avoids errors.

3. Consult your ERP provider
Contact your system provider and ask:

What are the upgrade plans to meet the requirements of the Tax Reform?

What functionalities will be changed?

What is the schedule for these changes?

Whether there will be additional costs or a need to migrate to another version.

4. Automate tax calculations
The Reform aims to simplify, but it also brings new rules for calculation. Having an ERP that automates tax calculations, avoiding manual errors, will be essential. This reduces risks, rework and problems with the Tax Authorities.

5. Integrate the ERP with specialized tax solutions
Not all ERPs have robust tax modules. Therefore, considering integration with intelligent tax platforms can be strategic. They offer:

Automatic updating of tax rules.

Correct generation of accessory obligations.

Validation and auditing of tax data.

6. Train your team
Success in adapting to the Tax Reform also depends on people. Tax, accounting, IT and finance teams need to understand how these changes impact processes and how to correctly use the new ERP resources.
